Correct Answer: A

Rationale: The nurse should first administer aspirin to a client with chest pain as it helps prevent blood clot formation during a possible heart attack. Aspirin inhibits platelet aggregation, reducing the risk of further blockage in the coronary arteries. Administering aspirin promptly can improve the client's outcomes. Performing an ECG, monitoring vital signs, or providing a meal plan are important but should come after administering aspirin in the initial management of chest pain to prioritize the client's safety and well-being.

Correct Answer: B

Rationale: The correct answer is B: Vitamin B12. Strict vegetarians, especially those who exclude all animal products, are at risk of Vitamin B12 deficiency as it is primarily found in animal products. Vitamin C (A) deficiency is more common in those with poor fruit and vegetable intake. Vitamin E (C) deficiency is rare and usually seen in individuals with specific medical conditions. Magnesium (D) deficiency can occur in individuals with poor dietary intake or certain medical conditions, but it is not the primary concern for strict vegetarians.

Correct Answer: D

Rationale: The correct answer is D (Morton's neuroma) because interventions for difficulty walking due to a foot mass include recommending proper footwear, orthotic devices, corticosteroid injections, physical therapy, and in severe cases, surgical removal of the mass. Morton's neuroma causes pain and tingling in the ball of the foot, leading to difficulty walking. Plantar fasciitis (A), Hallux valgus (B), and Hammertoe (C) do not typically present with a mass in the foot causing difficulty walking.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. Epinephrine is the first-line treatment for anaphylaxis as it helps to quickly reverse severe symptoms by constricting blood vessels and opening airways. Administering corticosteroids (B) is not the immediate priority. Placing the client on their side (C) is important to prevent aspiration but does not address the anaphylactic reaction. Monitoring blood pressure (D) is essential but administering epinephrine takes precedence in managing anaphylaxis.
